COLLATING DEVICE FOR'PRIN'IING-PRESSES.

Specification of Letters Patent.

Continuation in part of application Serial No. 817,567, filed February 9, 1914. V This application filed May 2, 1914. Serial No. 835,847.

To all whom it may concern: 7

Be it known that I, EMERSON P. JEN- NINGS, Jr., a citizen of the United States, residing at Lehighton, in the county of Carbon and State of Pennsylvania, have invent- This invention relates to a collating device for printing presses and is designed more particularly for use in connection with a bed and platen press, but is capable of ap; plication to any press inwhich the Web of paper is fed forward between'the making of the impressions and held stationary while the impression is being made' The object of the invention is to provide a device which will separate that portion of the web 'upon which each impressionis made into two or more parts and pile these parts one on top of the other. 7

It not infrequently happens that where a small form is used it is desired to duplicate this form on the form-bed, arranging the forms one beyond the other lengthwise of the sheet, and if the complete impression is severed from'the web it becomes necessary to later re-cut the severed portion of the web to separate the impressions taken from the different forms.

To accomplish the desired result it is a further object of the invention to provide means whereby the cutting device for sev-' ering the impressions from the web may be so timed with relation to the movement of the printing couple as to operate upon the web two or more times between the making of two successive'impressions,'thus causing that portion of the web on which the impression was made to be divided into two or more parts,"as may be desirable.

In the accompanying drawings, Figure 1 is a side elevation of a press embodying my invention; Fig. 2 is a sectional detail view of the. interchangeable gears for varying the speed "of the cutting andv feeding mechanism, and Fig. 3 is a detail'view of the ad justable drive for the feeding device to vary the length of the feed. V

In these drawings I have illustrated one embodiment of my invention and have shown the same as applied to a printing press in which the printing couple comprises a fixed platen and a form-bed movable in a substantially right line toward and away from the platen, but it will be understood that this type of press is chosen for the purposeof illustration only and that the invention is applicable to various types of printing presses, in which the web is held stationary during the taking of the impression and'adv-anced during the interval be tween the impressions. a

I n carrying out my invention I provide means for advancing the web between suc cessive impressions a distance equal to the length of the form or the combined length of the several forms on the-form-bed, and means for severing that portion of the web so advanced into two ormore' parts,the number of parts depending upon the number of parts into which the form is divided. Preferably, the feeding action is intermittent and the web is fed forward a distance less than the total distance which the web.

is to be advanced and the cutting mechanism actuated to sever that portion of the web and then the web is fed forward a second time for a similar distance and this portion of the Web severed and this'action repeated as many times as there are forms on the form-bed and-the several feeding and cutting operations taking place,during the interval between two operations of the printing couple.

In the present embodiment of the invention I have shown thesame as applied to a press comprising a main frame 1 having mounted therein a normally stationary platen 2, cooperating with which is a combined form-bed and inkingdrum 8 having movement toward and away fromthe platen. This movement is accomplished by mounting the combined form-bed and inking drum in slide blocks 4 which are mounted inside the members of the main frame, one block only "being here shown, and connected by pitmen meshing with a positively driven pinion '8 chain also passing about a sprocket wheel 11,

to which is rigidly secured a sprocket wheel Mounted on the axis of 12. Movement is transmitted through the second sprocket wheel, 1.], to the paper feed ing mechanism which is here shown as comprising a positively driven feed roller 13 and a cooperating pressure roller 14 arranged above the same. The feed roller 13 is provided with a pinion 15 which is engaged and actuated by a toothed segment 16'pivotally mounted at 17 and having a radial slot 18 in which is mounted a slide block 19, which slide block is also mounted on a wrist pin 20 carried by a rotatable disk 21 to which is rigidly secured a sprocket wheel 22. Obviously, the rotation of the sprocket wheel and disk will cause the segment to be oscillated about its axis and the feed roller 13 positively rotated. A. pawl and ratchet con nection is interposed between the pinion 15 and the roller 13 to cause the roller to be rotated in one direction only. hen the forms bed contains a single form only the sprocket wheel 20 is driven atthe same speed as the sprocket wheel 22, the connection being preferably formed by a single sprocket chain, but where a plurality of forms are mounted on the form-bed the sprocket 22 is driven at a speed greater than the speed of the sprocket wheel 12. In the present instance the formbed is shown as having thereon two forms 23 and it is, therefore, desirable that the feeding roller should be actuated twice. for each operation of the printing couple. To accomplish this I have interposed between the sprocket wheels 12 and 22 means for increasing the speed of the sprocket wheel 22 and causing the same to rotatetwice as fast as the sprocket wheel 12 rotates, thereby causing two operations of the segment 16 and the feed roller 18 in the same length of time in which these parts formerly made a single movement. This may be accom plished in various ways, but preferably I use a compound sprocket wheelconsisting of a large sprocket wheel 24 and a small sprocket wheel 25 rigidly connected to gether. The large sprocket wheel which, in the present instance, is a sixteen tooth wheel is connected with the sprocket wheel 22 by means of a sprocket chain 27, while the smaller sprocket wheel which, in the present instance, is an eight tooth wheel is connected by another sprocket chain 26 with the sprocket wheel 12. Consequently, the speed of the sprocket wheel 22 is twice that of the sprocket wheel 12. Preferably, the compound sprocket wheel is mounted on an eccentric stud 88 which, in'turn, is mounted in the side wall of the frame, to enable the sprocket chains to be adjusted. If the formbed were to carry three forms then the sprocket wheel 2 1 would be changed for a twenty-four toothed sprocket wheel so as to cause the speed of the sprocket wheel 22 to be tripled and a similar variation in the ratios of the sprocket wheels would be made to messes the wrist pin 20 adjustable so that the amount of movement imparted to the segment 16 can be regulated. This adpistinent is, in the present instance, accomplished by providing the disk 21 with a transverse groove 28 in which is mounted a slide block 29 which carries the wristrpin 20. l-lny suitable means may be provided for adjusting the slide block but, in the present instance, I have shown the same as having an extension 30 provided along one edge with teeth 81 meshing with a pinion 32. mounted on the disk and having a socket 33 to receive an actuating implement; The feeding mechanism just described is not a part of the present invention but forms a part of the subject matter of the application filed by me February 9th, 1914-, Ser. No. 817,567, in which this mechanism is fully illustrated, described and claimed, and it will be understood that any suitable feeding mechanism may be substituted therefor. I

The cutting mechanism is so timed with relation to the feeding mechanism that it will operate upon the web of paper at the end of each of the feeding operations, thus making as many cuts as there are forms on the form-bed and causing the impressions from the several forms to be individually severed and piled one upon the other as they drop from the cutter. In the present instance, the cutter mechanism is shown as comprising a fixed shearer bar 34 and a blade 35 mounted upon a carriage 36 which, in turn, is slidably mounted upon guide posts 37 carried by the frame of the press. This carriage is connected by pitmen 38 with an eccentric 39 mounted on a shaft 10 which is driven by a sprocket wheel 4L1 and a sprocket chain d2 from a sprocket wheel 43 on the axis of the sprocket wheel 22. The operation of the press will be readily understood from the foregoing description and it will be apparent that the Web of paper is fedin the direction of the arrow in Fig. 1 and that at each operation of the printing couple it receives an impression from the several forms, or they may be parts of the same form, carried by the form- 'bed 3. When the impression is made and the two members of the printing couple separate the feeding mechanism draws the web forward a distance equal to the combined length of the forms or parts of,the forms. The advancement of the web is preferably, but not necessarily, intermittent and the cutter is so actuated as to cause it to operate upon the web a number of times corresponding to the number of forms on the formbed, and, where the feed is intermittent, the number of cuts corresponds to the number of feeding operations.

While I have shown and described one embodiment of the invention it will be understood that this has been chosen for the purposes of illustration only and that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a printing press, the combination, with a printing couple comprising a platen and a form bed, one of said members having movement toward and away from the other, said form-bed being adapted to support a plurality of forms arranged lengthwise of a web of paper to engage the same upon each operation of the printing couple, actuating means comprising a shaft to impart movement to the movable member of said printing couple, of a feeding device,

and actuating means for said feeding device comprising a sprocket wheel secured to said shaft, a second sprocket wheel connected with said feeding device, a stud mounted on said press between said sprocket wheels, two other sprocket wheels, of different sizes,

mounted on said stud and connected one to the other, and chains to connect the lastmentioned sprocket wheels, respectively, to the two sprocket wheels first mentioned.

2. In a printing press, the combination, with a printing couple comprising a platen and a form-bed, one of said members having movement toward and away from the other, said form-bed being adapted to support a plurality of forms arranged lengthwise of a web of paper to engage the same upon each operation of said printing couple,
